UNITED STATES F Raymond Liona, Bmokly-MN' Y.. AppIicatitIrAiugust-IG, 1946; SerialNo. 6903902 provision of guide means oi this type which are of a general utility; that is to saygguides which are of advantage; because of their utility and novelty, for automatic presses and also for those using hand means, and guides which call for no space or occupied: area". 0:12, the margin, of the platen workpiece.

This invention, -msreover, has tor objects thereof the provision of guides which are in- ?Xpen's'ive to manufacture, simple, consistent with eilici'ency; and effective for holdingtheedge of a piece, of paper on' the platen; of the machine, in such manner that when the pri'nting' done it will register in the proper position on the paper; also to construct the devicein such manner that may be used inextending beyond the? edge of 1 the platen, so as toboth; support and g'uid'ethe paper; tomake the device-insuc'h way thatit will not injure the platen sheet or'ftear the same when being used"; andit consists, essentially, of a holder comprising a horizontal portion and a downwardly-extending flange adapted to be gripped between the platen and the bail II, for example, and a strip slidably held on said hori zontal portion and having guiding means at one end, the various parts of the device being constructed and arranged in detail, as hereinafter more particularly described.

With the above indicated objects and advantages in view as well as others which will hereinafter appear, the invention resides in certain novel constructions and arrangements of parts, the essential features of which are herein fully described, and illustrated in the accompanying drawing, in which:

Fig. 1 is a view in perspective of a printing machine platen, on which are shown in plural numbers embodiments of the instant invention.

Fig. 2 is an enlarged section on the line 2--2 of Fig. 1.

Figs. 3 and 4 are respectively top and underside views of a feed guide shown in Fig. 1.

Fig. 5 is a plan view of another guide shown in said Fig. 1. I

Fig. 6 is a section on the line 66 of Fig. 5.

3.,Claimss (Cl. Idle-415 cludes a platen I!) having edge clamping means II, II, and a sheet, as I 2 of paper, disposed in Working position thereon.

guide meansfor' the workpiece I 2 includes awunit having asheet metalleaf member I3 with a slot I4" therein running from: the split: end I5 thereof.

Slid'ably; embracing the leaf I3 is a member Hi, the latter having two side flanges-1 F, f1, embracing said leaf, and the" body portion I 6 thereof is an aperture, which receives a releasable holding element in the form of a bolt I8 having-a:- nut I9;

- Eependingirom the member this aflange which theworking position findsaseat inside cf'the clamp H and on the opposite end of the device, on the member I3, is a suitably limited depending guide flange 21. At this point it is 'notedthat in Fig. 1 is shown a pairof the guide units, and the members of this pair are alike, so that a description of one isapplicable to the other-.

At; the' juncture of'the flange?! with its body member #3 isa pairofapertures 22, 22' between which may also be an aperture 23, for a" third pin if three pins are used instead of two. Passing through the apertures 22 are the terminals 24, 25 of a wire extension having a looped medial part 26 slidably embracing the member I3 thereat. The adjacent edge of the sheet I2 enters against and engages the flanges 2|, 2i, and the terminals 24, 25 are so arranged (see Fig. 2) as to be advantageously disposed above and adjacent the margin of said sheet.

Substantially similar to the guides having the flanges 2| engaging the edge 30 of the workpiece I2 is a guide means having a flxed wire extention I25 overlying and thereby engaging the sheet I 2 at its margin 3:, this modified guide means including a projecting member H3 similar to member I3'and having a slot II4. Embracingly disposed on the member I I3 is a transversely disposed member H6 having side flanges I I1, and adjoining the member H6 with its flanges, are keeper elements 32, 32, while screw or bolt IIB retains the member I I6 slidably in position. The member H3 passes through slots in the member I I6 at the folds of the flanges I II. An anchorage flange IZI forms a portion of a leaf member 35, also embraced by the flanges II! and this member may have thereon channel shaped keeper elements 36, 36 with flanges I36, I36 engaging the edges of member 35 to guide the same.

As shown in Figs. 7, 8, a. flat leaf member 2I3,

As shown in said drawing, the disclosure inshown in side elevation and end elevation, has

thereon a guide flange 22 l at one end and a hinged anchorage flange 220 at the other end, as Well also as a member 2l6 and holding means 18.

In this latter case a wire extension means 228 may have its terminals as 225, upwardly turned, as shown. Between the member 2l3 and its hinged anchorage 220 is a torsion spring 38 mounted on hinge 2H, which tends to urge the flange 22l downwardly against the platen f0, and this guide means may therefore be swung upwardly to be automatically returned by said spring.

In the form shown in Fig. 9, a sliding member 3| 6 has an upwardly extending flange 32l provided with apertures to receive terminals 324, 325 of a wire extension 328, slidably mounted on the member 3I6 and held inadjustment by a screw '8.

Variations may be resorted to within the scope of the invention and parts of the improvements may be used without others.

I claim:

1. Guide means for a printing press platen having an edge clamp or bail, the guide means comprising a sheet metal flat leaf member having a slot, portion extending inwardly thereon from one end thereof, a second transverse sheet metal member overlying a portion of the flat leaf member and having a depending flange adapted to be engaged between the edge of the platen and the clamp and having side flanges engaging the side edges of the flat leaf member and being extensibly slidable thereon, there being a bore in the second transverse memberregistering with the slotted portion in the first member, means retaining both members selectively through said bore, an end of the leaf member,

opposite from that in which the slot extends being imperforate and having a rigid depending guide flange, there being also a pair of apertures 2. Guide means for a printing press platen having an edge clamp the guide means including a flat sheet metal leaf member having a depending rigid guide flange for a workpiece on said platen, there being a pair of apertures in said flange, a generally U-shaped wire element having the intermediate portion thereof slidably engaging a portion upon said sheet metal leaf member and having the limbs thereon projecting through said pair of apertures and terminating beyond said leaf member, and an anchoring flange disposed at the other end of said leaf member for engagement between the clamp and the edge of the platen.

3. Guide means for a printing press having a. platen provided with a clamp, the guide means including a sheet metal leaf member having a guide flange upon one end with a perforation therein and a retaining flange at the other end adapted to be engaged between the clamp and the edge of said platen, and a narrow elongated member engaging with a portion upon said leaf member and having one end projecting outwardly through said perforation at a level above that of a work sheet lying upon said platen against the guide flange.
